Even though the writers have written it so Samuel seems to have manipulated Hiro to doin' what he wants, it's not like he doesn't have options.
I mean, maybe the storytellers don't choose this route, but couldn't Hiro just ask for a way back to the Carnival, and then do something other than what Sam wants? Knowin' the way back to the Carnival is kinda crucial, but if he gets that bit o' info, then I think it would be more in character for Hiro to decide to get things done his way instead of bein' manipulated by Sam.
Of course, he might not have a way of knowin' that Sylar has taken over Matt's body, but, to me, it makes sense that Hiro would go find Parkman('s body, at least) and ask him if he would go back with him to the Carnival and use his Jedi mind trick to extract the info from Samuel about where/when Charlie is, so that he can retrieve her. And then, that scenario would also provide a way for Gabe's consciousness to be in the same place as his body...
What do you think? Could that be a possible storyline?
Hiro could still do whatever Sam wants him to do (save Mo?), but havin' a back-up plan to find Charlie seems like something the writers should have him do...
